Leaving it alone - didn't even notice it was there. However, based on Google results lookup, I wonder if I should keep it? Per one of the posts, "Windows the Panther folder can easily fill up multiple gigabytes."

Note: I usually run the MS Disk Cleanup utility once a month using the "Clean up system files" option and checking all options including "Windows Update Cleanup". Maybe why my Panther folder is empty?

Kent,

Same here. It usually took 15 mins to a few hours to delete the Windows Update files, depending on the computer. After I installed Update 1 I noticed the Windows Update Cleanup took only 10 seconds but the C: drive used space didn't change. I repeated the Disk Cleanup scan and the Windows Update files were no longer offered.

I tried...

dism /online /cleanup-image /startcomponentcleanup

... and it uninstalled Update 1. That shouldn't have happened. So I restored an image, installed Update 1, ran Disk Cleanup as above and tried...

I did run cleanup a few days after Update 1. I also ran it again a few days after I installed the second part of update 1. I have no issues here as you can see from my screen-shot. Sorry as I know this offers no solution, only more questions...

I usually wait a few days after windows update and make sure my system has been rebooted several times before I run the disk cleanup. Just out of curiosity, do you do the same or do you run the cleanup very soon after the initial reboot to finish installing the windows updates? Just stabbing in the dark a bit trying to see if we did anything different...

I tried another clean-up today on my main computer and again experienced corruption. There is no common unusual software among my four affected computers. A fifth test computer cleaned up today without corruption. My first success.
